o This invention relates to articles of jewelry of that class, such asbroochesand the like, known as pins, .and the objects of the inventionare, first, to provide an improved construction of pin stem wherebythe'engaged portion of the fabric will be clamped between the pinbodyand the pin stem to hold the pin from tilting or sliding move--ments in any direction of the fabric; second, to provide a three-pointtensioning action of a spring-clamp pin stem whereby the pin clampingaction and the latching tension of its pointed end will be increased toprevent .any possibility of the pin shifting on the fabric .or ofthe'pin stem being unlatched even when the pin is fastened upon verythin and sheer fabrics; third, to'provide aspringclamp pin stem wherebythe pin may be securely clamped to ribbons or other fabrics 0 withoutpiercing the same; fourth, to provide for the use .of a spring pin stemfastened to the pin bodywithout soldering and without loss of springtemper due to a soldering action; and, finally, to generally improvethe5 construction and increase the holding efiiciency of the pin and toensure greater security against its accidental release from the garmentand loss.

The invention consists of the features of 0 construction, combinationand arrangement of parts, hereinafter fully described and claimed,reference being had to the accompanying drawing, in which Figure 1 is aside elevation of a bar pin embodying my invention, and showing the pinstem unlatched and in its normal untensioned condition.

Figure 2 is a similar view, show-ing the pin stem in latched position.

Figure 3 is a back view of a portion of the pin body and showing themeans for fastening the heel end of the pin stem thereto.

Figures 4 and 5 are cross-sections showing different forms of pin stemswhich may be employed.

pin, brooch, or of any other-desired form or shape, to which body a pinstem 6 is attached 1i for connecting the article. to the clothing "ofthe wearer, or to any other support. The body a is provided with alongitudinally and transversely flat rear face a at one end of which isdisposed the usual catch or keeper m to receive the point end of the instem, and at the other end of which is sodered or otherwise secured aretaining sleeve a fmade of suitable sheet metal.

The pin stem 5 is of novel and improved construction and comprises abody portion 0 terminating in heel and point end portions d and e, whichportions 03 and e are, offset at an angle outwardly and rearwardlywith'respectto the body 0. portions d and ethe pin stem body c'islongitudinally'bowed 0r. curved-in a direction toward the face a of thepin body a, whereby the pin stem is adapted for a novel and efficientclamping action, as hereinafter described. V

The heel end all of the pin stem has a return portion f which liesparallel with the plane of'the body face a and is adapted-for engagementwith the retaining sleeve a This return portion f is fitted inthe'sleeve when the bracelet parts are assembled and the sides of thesleeve are thensubjected to a crimping action at a plurality of spacedpoints, as indicated at g, to provide instruck projections, by means ofwhich the return portion of the heel end of the pin 'is' permanentlyfastened to the pin body a without the necessity of hitting the pin stemor directly soldering any Between these ,two end part thereof'to the pinbody, thereby avoiding all liability of reducing the temper of thespring material of which the pin stem is made.

The degree of bow or curvature of the body portion of the pin stem issuch that when the pin stem is closed and its point end-cengagedwith'the keeper W, the stemvvill be placed under an intermediate maintension, under which it is straightened out to a flat or substantiallyflat condition, as shown in Figure 2, and thus flatly engages thesurface .a of the pin body a or in any fabric interposed therebetweenthroughout the entire length of the pin stem body between its offsetportions 65 and c. It will be understood, of course, that the pin stemmay be used for fastening the pin to an article of clothing or piece offabric in the usual Way, that is by passing the pin through the fabricand engaging its point end with the keeper (L or that, when it is notdesired to pierce the fabric, the pin may be simply closed to bind thefabric Without piercing it between it and the pin body face'a. Where thepin stem is used to both pierce and clamp the fabric, it is obvious thatthe pin will be held firmly and prevented from turning or tipping on thepin stem out of proper position, the double engagement enablingthe pintobe secured to even the finest and most delicate fabrics Without injuryto the latter and without shifting out of its proper display position.

The novel structure of the pin stem which adapts it for a clampingaction throughout ts ength enables the pin to be secured to fabricswithout piercing the latter, such use being particularly advantageous inapplying the pin to ribbon supports of various widths so firmly as toobviate any liability of casual displacement of the pin or its possibleloss. To increase its clamping efficiency the pin stem may betransversely flat, as shown in Figure 4, so as to provide a fiat bearingface 0 or, as shown in F igure '5, it may be of half round form so as toprovide it with at least an inner flattened face 0?. However, the pinstem-may be made of circular cross-section throughout, if desired.

, In the operation of closing the pin stem, the portion of the stem bodyadjacent the end (Z first comes in contact with the pin bodya, so thatthe offset heel portion (Z is placed under tension, the bowed bodyportion of the pin stem then progressively comes into contact with thepin body and is flattened out and placed under tension, and finally thepin portion 6 of the pin stem is forcibly brought into engagement withthe keeper o to latch the pin stem, in which action it will be placedunder tension, so that when the pin stem is closed its flattened bodyPOItlQIl will clamp the fabric by its own ten- SiO I1-, throughout itslength, and by the auxiliary tension of each of the end portions d and'6, so that a maximum firmness and securityof clamping engagement isobtained.

7 By securing the pin stem to the pin body spring temper may be producedand applied without its temper being impaired, so that a clamping pinstem of maximum efficiency 7 will be furnished. I

In th modified form of the invention shown in Figure -6, the spring pinstem is elongated rod-like brooches, stick pins, hat ornaments, lodgepins, etc., where the article is of restrictive width and both mainparts thereof may be readily made from a single kind of material and asa unitary article of manufacture.

Having thus fully described my invention,
